compatibility - springdoc-openapi + Spring 4 兼容性

Question

我有一个现有的 Spring 4 API，并已成功集成 springdoc-openapi 以在 JSON/YAML 中生成 OpenAPI 3 规范，还使用 ​​springdoc-openapi 1.2.29 和 Spring Boot 15.2.2.RELEASE 显示 Swagger UI，但是在 springdoc-openapi 的更高版本中似乎修复了各种错误并添加了增强功能。不幸的是，如果我使用高于 springdoc-openapi 1.2.29 的版本，我会遇到 Spring 4 的各种兼容性问题。

是否有 springdoc-openapi 和 Spring 4 的可用性兼容性矩阵？当我通读 springdoc-openapi 文档时，我没有看到任何自述文件或发行说明表明存在 Spring 5 要求，但是如下所述，一旦达到某个版本，底层 springdoc-openapi 中就会使用 Spring 5 类。

我的相关 POM:

    <!-- springdoc-openapi-ui -->
    <!-- anything over 1.2.33 uses Spring 5 MethodParameter.getParameter()-->
    <!-- anything over 1.2.29 uses Spring 5 org.springframework.http.codec.multipart.FilePart -->
    <!-- webjars-locator-jboss-vfs is required for running under JBOSS and exposing the swagger-ui -->
    <dependency>
        <groupId>org.springdoc</groupId>
        <artifactId>springdoc-openapi-ui</artifactId>
        <version>1.2.29</version>
    </dependency>
    <!--  
    <dependency>
        <groupId>org.springdoc</groupId>
        <artifactId>springdoc-openapi-security</artifactId>
        <version>1.2.29</version>
    </dependency>
    -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot</artifactId>
        <version>1.5.22.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-autoconfigure</artifactId>
        <version>1.5.22.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.webjars</groupId>
        <artifactId>webjars-locator-jboss-vfs</artifactId>
        <version>0.1.0</version>
    </dependency>

当使用 springdoc-openapi-ui 1.2.30 时，它随后会引入 springdoc-openapi-common-1.2.30.jar，它会在尝试使用 org.springframework.http.codec.multipart.FilePart 时抛出异常。同样，使用 1.2.34 或更高版本将在 MethodParameter.getParameter() 上抛出异常。

public interface FilePart
extends Part

Specialization of Part that represents an uploaded file received in a multipart request.

关于如何解决此问题以在更高版本中利用 springdoc-openapi 中的错误修复和增强功能的任何建议？

问题已确认并将作为 1.3.3 的一部分得到解决。请查看下面使用 Springdoc 记录的问题。感谢@bnasslahsen 令人难以置信的快速识别和更正!
